Dodgers vs. Mariners SGP predictions Sept. 27: Look for Naylor to stay hot, fade Ohtani vs. Gilbert

Dodgers vs. Mariners predictions

A pair of division winners do battle in the Pacific Northwest tonight, as the Seattle Mariners host the Los Angeles Dodgers.

The pregame narrative: Both teams have already locked in their playoff seedings, so there’s nothing of note to play for. It’s still a marquee matchup, though, with Tyler Glasnow and Logan Gilbert on the mound.

Check out these Dodgers vs. Mariners SGP predictions for Sept. 27, featuring Shohei Ohtani and Josh Naylor.

Dodgers vs. Mariners predictions

Parlay: Ohtani over 1.5 total bases | Naylor over 0.5 hits | Under 8.5 runs (+295)

Ohtani under 1.5 total bases (-134): I hate betting against Ohtani, but this is a playable number with Logan Gilbert on the mound.

Ohtani walks a lot and strikes out a lot, and both of those things are good for this under.

Against Gilbert, Ohtani is 4-for-15 (.267) with seven strikeouts and five walks.

Seattle’s right-hander has 37 plate appearances against the rest of the Dodgers lineup and hasn’t walked anyone. He tries to be avoidant around Ohtani, and I totally understand that.

Ohtani is waltzing to his fourth MVP award in five seasons. He’s averaging 2.4 total bases per game.

One titanic swing can ruin this, but I’m riding with the under based on a history against Gilbert that works in my favour.

Also, Ohtani has gone under 1.5 bases in 18 of his past 32 games.

MLB SGP legs

Naylor over 0.5 hits (-195): As a standalone wager, I’d be looking hard at Naylor over 1.5 bases for tonight. He’s on a serious heater, and the +150 price point jumps off the page.

For this SGP, though, I’ll go with the safer route of one hit. Naylor is batting .364 this month and is 18-3 vs. this prop.

He’s also on a 12-game hit streak, which has been a thing of beauty:

  • 19-for-44 (.432)
  • 10.4 K%
  • 4.2 BB%

Naylor has a 90th-percentile strikeout rate, per Baseball Savant, so his low K% during this streak isn’t much of a surprise. The low walk rate is nice to see, too, since walks don’t help with this prop.

Against Glasnow, Naylor is 1-for-3 in his career.

Under 8.5 runs (-180): Both teams have potent offences, but I like this under with two stellar pitchers on the mound.

  • Both Glasnow and Gilbert have sub-3.50 ERAs and sub-3.90 FIPs.
  • This under is 8-4 in Gilbert’s 12 starts since the all-star break.
  • This under is 10-7 in Glasnow’s starts this season (and three of the overs finished with exactly nine runs).

The Dodgers average 5.1 runs per game, which is the second-highest total in MLB, but they tend to play low-scoring games on the road. Unders are 43-33-1 in L.A.’s road games this season.

Last night’s series opener finished as a 3-2 win for the Dodgers.
